Heather Morris Hacked

"The naked pictures are alleged to have been stolen by hackers from the 25-year-old actress's mobile phone," writes Sophos' Graham Cluley.

"In November 2011, Christopher Chaney of Florida pleaded not guilty to hacking into the email and cellphones of some 50 people, including Scarlett Johansson and Mila Kunis," Cluley writes. "He has claimed he was driven by 'addiction' and apologised for his actions, but denied selling private celebrity photographs to websites and magazines. There's no suggestion that Chaney is involved in the latest incident involving Heather Morris."
